To calculate the area of a triangle, we use the formula:
\[
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
\]
Let's solve for each triangle step by step.
Triangle 1:
- Base = 10
- Height = 14
\[
\text{Area} = \frac{1}{2} \times 10 \times 14 = \frac{1}{2} \times 140 = 70
\]
Triangle 2:
- Base = 5
- Height = 9
\[
\text{Area} = \frac{1}{2} \times 5 \times 9 = \frac{1}{2} \times 45 = 22.5
\]
Triangle 3:
- Base = 6
- Height = 6
\[
\text{Area} = \frac{1}{2} \times 6 \times 6 = \frac{1}{2} \times 36 = 18
\]
Triangle 4:
- Base = 2
- Height = 8
\[
\text{Area} = \frac{1}{2} \times 2 \times 8 = \frac{1}{2} \times 16 = 8
\]
Triangle 5:
- Base = 5
- Height = 12
\[
\text{Area} = \frac{1}{2} \times 5 \times 12 = \frac{1}{2} \times 60 = 30
\]
Triangle 6:
- Base = 7
- Height = 3
\[
\text{Area} = \frac{1}{2} \times 7 \times 3 = \frac{1}{2} \times 21 = 10.5
\]
Final Answers:
\[
\boxed{70, 22.5, 18, 8, 30, 10.5}
\]
